MACHINE FOR IVIAKING PAPER BAGS AND BOXES.

Specification of Letters Patent No. 82,777, dated July 9, 1861.

To all whom, t't'wiiiii coat earn:

Be it known that I, JOHN M1LLER, Jr., of Baltimore cit'y, Maryland, haveinvented a new and Improved Machine for Making Boxes of Paper; and I dohereby declare the following is a clear and exact description of theconstruction and operation of the same, reference being had to theannexed drawing, making a part of this specification, in which Plate 1Figure l is a perspective view accompanied by details. Plate 2 Fig. 2 isa longitudinal view accompanied by details.

My machine consists of a table or platform A which receives the paper instrips or sheets previously reduced to the desired width and which arefed or moved forward between guides A to their proper place by thefinger points B attached to arm G which is jointed on the rockershaft 1) and regulated in its length of stroke by the set screw E andmoved forward and backward by the bar or lever F hinged to the cutter Gand working through a slot in the axle of the rocker shaft D which givesthe feeder an irregular motion causing it to move slower at the startand. ending thereby preventing the finger points B from slipping theirhold on the paper and effecting the moving and adjusting of it withcertainty. There are incline planes A on the guides A which elevate thefinger points B from the paper at the commencement of their returnstroke and prevent its being moved forward until the knives of thecutter G have been raised sufliciently to clear it thereby preventingits catching against them. The cutter G cuts off the proper length ofpaper to form the box and at the same time makes the cuts for the bottomand sides of the next succeeding box. The cutter G is moved in itsproper time by the segment of cog wheel H working 011 the pinion I whichis connected by the crank I and strap K to the bar or cross head L whichis attached to cutters G. The paper when out and moved forward asdescribed is pressed by the piston M through the box or mold N havingcurved sides or ends of such form as to fold the paper to the desiredshape. The glue or paste is applied to the paper in its passage throughthe molds N by the circular brushes 0. O. O. 0. working through openingsin the mold N the glue or paste being supplied to the brushes 0 by thefountain P which has openings Q, Q, Q, Q, regulated by the sliding lidsR R adjusted by screws S, S, so as to give the desired space for theflow of the glue or paste which is taken up by the brushes 0, O, O, 0working over said openings. The paper while receiving the glue or pasteis pressed against the brushes 0 O O O by the cams T T T T.

There are connected to the mold N clasps or bars U U U U pressedtogether by the springs V V V V, which clasps or bars receive the boxesfrom the piston M and retain them in shape for the purpose of givingtime for the glue or paste to set until the return of the piston withthe succeeding box which then takes a similar position the former boxesbeing pushed or dropped therefrom, the clasps or bars U U U U areregulated in the pressure by the set screws X X X X.

What I claim as new and desire to secure by Letters Patent, is

l. The combination of the crosshead L, lever F, rock shaft D, adjustablearm C, and fingers B, constructed and operating substantially asexplained to impart an intermittent feed movement to the strips ofpaper.

2. The cutter G, constructed as shown and described and operating inconnection with an intermittent feeding device substantially as and forthe purpose set forth.

3. The mold or folder N, constructed as described and operating inconnection with a suitable plunger substantially as and for the purposesset forth.

l. The combination of the rotary brush 0, fountain P, and pressure camsT, operating to paste or glue the boxes while passing through the moldsas explained.

5. The spring clasps U V, applied beneath the molds N, employed to holdthe oints of the boxes until set, as hereinbefore explained.
